Ieee80211Receiver¶

Package: inet.physicallayer.wireless.ieee80211.packetlevel

compound module Ieee80211Receiver

This receiver model receives an IEEE 802.11 transmission successfully if the minimum of the signal to noise and interference ratio over the duration of the reception is sufficiently high. It uses one of the IEEE 802.11 specific error models to compute the error rate based on this value and the used operation mode.

snirThreshold	double		Reception is not successful if the SNIR is below this threshold (unsuccessful reception)
snirThresholdMode	string	“min”
energyDetection	double		No signal is detected at all below this reception power threshold (idle state)
sensitivity	double		Reception is not possible if the signal power is below sensitivity (idle or busy states)
centerFrequency	double		Center frequency of the band where this receiver listens on the medium
bandwidth	double		Bandwidth of the band where this receiver listens on the medium
modulation	string	“BPSK”	One of “BPSK”, “16-QAM”, “256-QAM”
